Handling ICS enhanced and non enhanced MSC in a pool

摘要

The invention related to handling core network entities of a radio core communications network comprising a first network entity and a second network entity. The said second network entity differs from the first network entity in that it is capable of processing interworking between messages exchanged with said radio core communications network and messages exchanged with an IP multimedia subsystem. In other words, one network entity is capable of performing inter-working while the other one not. The first and/or second network entities are provided (S200) with configuration information indicating a relationship between the two network entities. The invention then foreseen routing (S300) messages relating to calls established between the at least one user terminal attached to the entity non capable of inter-working and a further user terminal attached to said IP multimedia subsystem according to said configuration information.

主权项

1. A method for handling core network entities of a radio core communications network, the radio core communications network comprising a first network entity and a second network entity, wherein the second network entity differs from the first network entity in that it is capable of processing inter-working between messages exchanged with the radio core communications network and messages exchanged with an IP multimedia subsystem, the method comprising the steps of:
providing at least one amongst the first and second network entities with configuration information, the configuration information indicating a relationship between the first and second core network entities; routing messages relating to calls established and maintained between a first user terminal attached to the first network entity and a second user terminal attached to the IP multimedia subsystem according to the configuration information.
